I would like to use this mediun to announce an open source project i've been working on,
http://jsmarka.com - a JavaScript code performance benchmarking app...it helps in testing the performance of your JavaScript code, built with the benchmark.js library.
Jsmarka is basically just like jsPerf, but with a much better UI/UX, its available on github http://github.com/kodejuice/jsmarka, open to contributions...its still in it's early stage, some features are missing and 'would so much appreciate contributions from Open Sourcerers, feedbacks are highly welcome.
